Answer:
The third one :)
Step-by-step explanation:
(-4-(-7)) / (1-7) = (3) / (-6) = -1/2 = slope
Answer:
see explanation
Step-by-step explanation:
Given
(x - 2)² + 9 = 0 ( subtract 9 from both sides )
(x - 2)² = - 9 ( take the square root of both sides )
x - 2 = ±
yields no real solutions
There is no real number when multiplied by itself gives - 9
In fact the solutions to
are said to be imaginary, that is ± 3i
where i =
